Solid state lasers emitting at very short wavelengths (>10nm) are very attractive for several applications in material proce3ssing and holography, but not yet demonstrated. Physical limitations prevent using classic laser schemes. We present a semi-empirical and rigorous demonstration of the feasability of a solid state x-ray laser and find some relations of the suggested scheme with EIT (Electro-Magnetic Induced Transparency) and Lasing Without Inversion (LWI).
